IMPROVEMENT IN LAMP-CHIMNEYS.

The Schedule referred to in these Letters Patent and making part of the lame.

Torall whom 'it may concern:

Beit known that I, CHARLEs H.Wonco'rr, of Randolph, in the county of Oattarangus, and State of New York, have invented a new and improved Method of Securing Lamp-Chimneys to Burners; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and. use the same, reference being had to the accompanying drawings forming part of this specification.

The object of this invention is to provide a more simple and secure means for securing glass chimneys to oil and other lamps.

My invention consists in providing lugs or vertical planes upon the ends of a lamp-chimney, provided with two or more inclined anges, so as to prevent the flanges from being passed beyond the hooks that secure the chimney.

Figure l represents a side elevation of la chimney secured according to my improvement to a burner, which is partly broken away.

Figure 2 represents a horizontal section of the chimney on the line :v a: of g. 1.

Similar letters of reference indicate corresponding parts.

A represents a chimney, which is constructed with theinclined curved flanges B, having lugs or vertical projections, C, at their highest ends.

The said flangesare arranged so as to provide a space between the point of one and the heel of the other.

D represents hooks on the burner as in the ordinary construction, which, when used according to my improvement, must be fixed opposite to each other radiall Tlie chimney is secured to the burner vby placing it thereon with the said spaces between the flanges eoincident with the hooks, thereby admitting the bottom of the chimney to pass below the hooks.

Then, by turning the chimney a part of a revolution on its axis, thefianges passing under the hooks will be clamped tightly thereby.

In case the hooks are bent upward too much by use, the lugs C will prevent the chimney from turning so far as to bring the spaces under the hooks, whereby the chimney would be liable to fall off.

I am aware that the inclined planes on the flanges B are not new.

What I claim, is-

The vertical flan ges C C, when arranged on the ends of the curved anges B of a lamp-chimney to check the chimney, all as herein shown and described.
